Temporary Anchorage Device as an Innovative Alternative for Unilateral Arch Mesialization in Medical Application

Abstract

Like any other medical intervention, orthodontic treatment has, in addition to its benefits, also associated risks and complications that are sometimes caused by wrongful treatment objectives. Correction of previous orthodontic malpractice is always a challenging problem in orthodontics. The present study aimed to introduce an innovative approach for total arch mesialization. In this study, the treatment course of a 25-year-old woman dissatisfied with her previous improper orthodontic treatment plan and unnecessary extraction of the upper and lower right first premolar teeth. Maxillary and mandibular dental midline deviation was evident concurrent with asymmetric dental arches and excessive gingival display a smile. The proposed corrective treatment plan consisted of right side temporary anchorage devices assisted total arch mesialization in both maxilla and mandible, followed by orthognathic surgery at the end. The patient’s final occlusion and facial profile improved significantly after the second treatment. The result was determined to be stable over a 1-year period. No significant evidence of root resorption was detected. Overbite decreased from 95% to 25%. Yaw correction was completely accomplished, and the final lateral cephalometric analysis after orthognathic surgery showed skeletal cl I relationship, normal proclination of upper and lower incisor teeth, and no evidence of periodontal complication and loss of vitality in the mandibular and maxillary teeth. The unilateral mesialization approach used in the current study prevented invasive therapies such as dental implants employing a special approach, which is less aggressive and more durable for the patient and revealed successful results with minimum side effects.
